Yeah, that's it. That is basically the CPR Aquafuge design. Now the understandably confusing part is the outflow. In the step 8 pic, the white return section has the final 90 elbow pointing slightly sideways. Maybe halfway from straight forward to right sideways. Once the whole thing is running, the outflow will be noisy, and you can quiet it by turning the whole white section clockwise, so the outflow end is pointing more UP. Eventually you'll get to a point that is the quietest it can get. It won't be perfect, but that's all there is to it.
